What should a patient know before the performance of a computed tomography examination?

Prior to the CT examination, the patient must remove all metal containing clothing items or jewellery. It is advisable not to eat for 3 – 4 hours prior to examinations that involve intravenous injection of contrast substance.


Upon the performance of the CT examination, the patient is placed on a special table around which the X-Ray tube rotates during examination. The examination is not painless or unpleasant to the patient.
